Can Mac Studio M2 Ultra 192GB run Qwen3.5-122B-A10B?

Apple · 192 GB LPDDR5 · 800 GB/s bandwidth · Alibaba · 122.0B (active 10.0B) · MoE · model ctx up to 256K

Yes — the Mac Studio M2 Ultra 192GB (192 GB LPDDR5) can run Qwen3.5-122B-A10B. At Q4 with the default 8K context it needs ≈ 70.1 GB VRAM (weights 67.1 GB + KV cache 2.0 GB + 1 GB runtime overhead), which fits within 192 GB. Decode at Q4/8K: ≈ 50.9 tok/s (estimated, batch 1). FP16 needs ≈ 247.0 GB — does not fit on this card. Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s. Methodology.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	69.1 GB	Yes	50.9 est.
Q4	8K default	70.1 GB	Yes	50.9 est.
Q4	32K	76.1 GB	Yes	50.9 est.
FP16	4K	246.0 GB	No	24.4 est.
FP16	8K default	247.0 GB	No	24.2 est.
FP16	32K	253.0 GB	No	23.0 est.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s means the model is far beyond this card (offload-only territory).
